Adjusting the height of the support wheels

With implements that are equipped with hydraulically lifting parallelograms, the height of support wheels must be positioned such that the upper guide pin 2 of the hydraulic cylinder 3 is positioned at the centre of the elongated slot 1 when the parallelograms are in working position.

If more lifting height is required, the height of the support wheels can be positioned such that the upper guide pin of the hydraulic cylinder is positioned at the upper end of the elongated slot. In this case, however, it must be ensured that the parallelograms are not lifted out during hoeing operation.

For implements that are equipped with mechanically lifting parallelograms, the height of the support wheels must be positioned such that the top link bars 1 of the parallelograms run parallel to the ground 2 when in working position.

  1. Lower the implement on the field with the three-point power lift.
  1. Loosen the nuts 1 of the clamp bolts 2.
  1. Slide the support wheel 1 up or down in the head tube 3 with the fork stem tube 2 until the support wheel is in the right position.
  1. Turn the upper clamp 3 on the fork stem tube 4 so that the steering stop pin 1 is centred between the two stop lugs 2.
  2. Tighten the nuts of the clamp bolts.
  3. Align the support wheel in the same way on the other side of the implement.
